Looks like I should give more info. I have not driven car yet, so I don't know about cooling while driving. The 11:1 compression engine is not broken in yet, so that should help. I am using the low mount cooler in front of the radiator that most use for an
oil cooler to cool my trans. Radiator is Griffin with double 1.25" tubes as large as I can fit in car. 180 thermostat. I may be hasty in my fan decision. Fan is 16" Perma-Cool High Performance Line. Do I have enough fan? I put the shop fan in front and that helped a bunch. Any ideas? Later, David.
